entrenched
UK: ɪnˈtrentʃt | US: ɪnˈtrentʃt
adj. (of an attitude, habit, or belief) firmly established and difficult to change
adj. (of a military position) securely fortified or defended
The word "entrenched" originates from the military practice of digging trenches (deep ditches) for defense. The prefix "en-" (from Old French) means "in" or "into," while "trench" derives from Old French trenche (to cut), referring to the act of digging defensive ditches. Over time, the term evolved metaphorically to describe ideas or habits that are deeply "dug in" and resistant to change, much like a fortified position.
